configuration/createHudsonJobForBug.sh now accepting Bugzilla API Key

[axeluhl]

If you'd like your shiny new build job that you create using the configuration/createHudsonJobForBug.sh script to include the bug's summary in its description, set your BUGZILLA_API_KEY environment variable to an API key you obtain from https://bugzilla.sapsailing.com/bugzilla/userprefs.cgi?tab=apikey or pass the API key as the second argument, after the bug ID, as in

./configuration/createHudsonJobForBug.sh 12345 {Bugzilla-API-Key}
